The Quockrans were a sentient species of slugs native to the planet Quockra-4. The species had a large, fat body that tapered to a tail. Their torso also had two arms, ending in stubby digits.

When the Minos Cluster was colonized late in the administration of the Galactic Republic, offworlders reached Quockra-4. The Quockrans responded to this violation of their isolation by manufacturing an entire society of droids to act as intermediaries
